Global Warming: What Scientists Want You to Know
Earth & Sky asked 500 scientists last week what they would like to tell the American people, right now, about global warming. Twenty-six wrote back; their responses make interesting reading, because they are personal. Some of the scientists work at U.S. universities and federal agencies; others work for international organizations or universities abroad. Check it out: http://www.earthsky.org/article/50989/20-scientists-speak.
Post your thoughts here. What made the largest impression on you?

I wonder how can global warming not be man made, we are using fosil fuels that had trapped the carbon underground and now put into the atmosphere by it's use.
As far as hurting the economy, what's wrong with industries ramping up production of jobs and products that would slow carbon burning. Industries devoted to better "green housing" , fuel efficent vechicles and recycling.
My relative just added insulaiton to there home, Their house is warmer now and they don't need to wear sweaters to stay comfortable, I drive less and use a Motorcycle to run errands. I remodeled my small house using current insulation codes and modern windows. It adds value and comfort as well as a much quieter house. I recycle. Instead of wasting money on going on far away places I stick closer to home and enjoy local events. I spend more time at home and enjoy reading and TV and the nature around me.
If a wealthy country like the US can't contribute to solving the troubles of the planet and be a leader. why should we expect the others of lesser means to even try. Why not try to do a little and perhaps you'll see a nicer way of life that doesn't damage our world as much, maybe you'll find out that it can be fun and fullfilling to give it a try. -
I once read an article written by some scientists that the ice ages were caused by the gravitational influences of a sister star to our sun. It seems that this star pair mutually rotate with respect to one another, and on the occasions that the sister star gets a bit closer to our solar system, it changes the eccenticity of the earths orbit around the sun (orbit becomes less circular and more elliptic). Since the earth spends more time farther from the Sun, winters get longer and summers shorter; thus the buildup of ice (iceage). As time goes on, the process is reversed, and on to infinitium. If true, puny man can not have much impact on large scale global changes.Now mankind is probaly contributing some to global warming, but the major cause could very well be increased volcanic activity beneath the oceans that both heat the oceans and put C02 in the atomosphere. We should cut down on the use of fossel fuel useage to help the situation, but primarily to wean ourselves off of Middle Eastern oil; thereby, decreasing our current security vulnerbility. And for God sake, don't ahere to the Kyoto Threaty which would would seriously damage our economy, while doing little to improve global warming visa vie the Chinese and India.

The Yosemite Valley was once filled with a glacier. The Saraha Desert was once the "Garden of Eden". Glaciers once went as far south as Indianapolis. None of these events had anything to do with the human condition. This seems to be how the earth works. Ice ages and earth warming trends seem to be a part of the earth's history. I doubt the last hundred years could have made much of an impact on the history of the earth.

I used the units provided and found if I burn 72 pounds of fuel I can produce 530 pounds of emissions. Just think how cheap CO2 is to produce. A laugh and a half from these goof balls. Just look at all the fire CO2 bottles we could sell.

You have the audacity to think for youselves and not revert to your caves. How could you not believe that cow flatulance in the mid-west was effecting global tempetures. These same hand wringers are the ones that bemoan the loss of the North American Bison, whose heards at one time would cover 4 states. With numbers that dwarf those of modern cattle heards. Evidently the Bison, were the now extinct, gas free bison. Who would have guessed that the Buffulo Skinners of the late 1800's were just attempting to save the environment.
You can't possibly be smart enough to ask the question, "If Green house gases are responsible for the hole in the Ozone Layer why do they appear over the antartic?". If modern industry is responsible for this (90% of industry is in the northern hemisphere) why not the artic? How long have we been able to detect a hole in the ozone layer? Is it possible that the holes are naturally occurring.
I personally believe that we have just experienced 10,000 years of extremely stable weather. If you don't think so look at the tempeture changes on Venus and Mars. If this a planetary problem compair the Earth to other planets we can observe. These scientists are basing their suppositions on 500 years of tempeture obeservations and ignore the glitches like the little ice-age of the midddle-ages. This is not science; it is people chasing GRANT MONEY in exchange for attesting to a political adgenda.
If global Warming is going to raise the level of the oceans. Why are we spending 10's of billions of dollars rebuilding a city that is already 10' below sea level.
Global warming is a good thing when you live in Maine.
